Site constraints 5

Habitat network: Network Enhancement Zone 2
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Radon affected area, class 5
An estimated 10 to 30% of homes reach the radon action level. Indicative for the 1 km square, which takes the highest class found in it; a radon test gives the answer for a building.
From the British Geological Survey and UK Health Security Agency indicative atlas. Under building regulations, as the BRE guide BR 211 (2023) sets out, new buildings and extensions need basic radon protection from class 3 in England and Wales and from class 2 in Scotland, and full protection from class 5. The class at the site itself, from the detailed BGS map, decides which.

Also on the record
Coalfield, development low risk area; Inside the Arlecdon built-up area; Natural England's Provisional ALC map (1:250,000, 1970s) had this area as grade 4, but it predates the buildings here and the current map does not class it as farmland.
Not affected
Outside flood zones 2 and 3 · Not green belt · No scheduled monument at the site

Checked on 6 October 2026. The pin for this application is the centre of its postcode rather than the building, so distances to nearby designations are measured from the postcode and can be out by the width of the postcode area.

A boundary can run through a site and the council holds the definitive record: confirm with the council before relying on this.
